How Lead Curtain Tracks Work — and Which Mounting Style Is Right for Your Room

Lead curtains are one of the most flexible shielding solutions available — they can be used in procedure rooms, imaging suites, doorways, and pass-throughs, and they require no construction to install. But the curtain itself is only part of the system. The track hardware that mounts and moves the curtain determines how well it works in practice, and choosing the right mounting style for the room makes the difference between a system that integrates cleanly into the workflow and one that becomes a daily annoyance.

This article covers how lead curtain track systems work, the differences between ceiling-mount and wall-mount installations, how to size the track for your room, and the accessories that complete the setup.

How the Track System Works

A lead curtain track is a length of 16-gauge high-strength steel — heavy enough to support even the densest curtains without deflecting. The curtain hangs from the track via wheeled dual-wheel carriers, one for each grommet along the top edge of the curtain. Grommets are spaced every 6 inches, with an S-hook at each one connecting the curtain to its carrier. This arrangement lets the curtain glide smoothly along the track and be pulled to one side when not in use.

The track itself includes connector brackets where sections join, end stops at each terminus to prevent the curtain from running off the track, and mounting brackets that attach to either the ceiling or the wall depending on the installation. Straight track sections handle most rooms, and curved track sections are available for rooms where the curtain needs to follow a non-linear path — wrapping around a corner, enclosing a U-shaped area, or following the perimeter of an imaging table.

Curtains wider than 4 feet are manufactured in multiple panels with overlapping flaps secured with heavy-duty Velcro strips, maintaining shielding continuity across the seam while allowing the panels to move independently on the track.

Ceiling Mount vs. Wall Mount

The two standard mounting configurations are ceiling mount and wall mount. Each has a distinct set of advantages, and the right choice depends on the room's layout, ceiling height, and how the curtain will be used day to day.

Ceiling-mount tracks attach directly to the ceiling structure or suspend from it via threaded rod or chains. This is the preferred configuration for most permanent installations — the track is overhead and out of the way, the curtain hangs freely from floor to the appropriate height, and there's nothing protruding from the wall to interfere with equipment or traffic. Ceiling-mount systems work well in imaging rooms, procedure rooms, and any space where the curtain needs to travel a longer distance or follow a curved path around equipment.

Intech's ceiling-mount track kits include straight and curved track sections, track connector brackets, track mounting brackets, end stops, and dual-wheel curtain hangers — everything needed for the installation except a drill, level, stud finder, and screwdriver. Track is priced per linear foot, so you order exactly the length your room requires. After order, Intech will confirm track layout and mounting requirements before shipping.

Wall-mount tracks attach to the wall above the curtain opening using heavy-duty wall brackets. This is a practical option for doorways, window coverings, and smaller openings where ceiling access is limited or where the curtain only needs to travel a short distance. Wall-mount hardware is available as an add-on bracket kit for installations that need additional heavy-duty mounting support beyond what a standard ceiling-mount kit provides.

In some installations both mounting methods are used together — ceiling track for the main run of a procedure room curtain, with wall brackets at the ends for additional support near the door frame or wall junction.

Sizing the Track for Your Room

Track is ordered by the total linear feet needed to cover the curtain's travel path. For a straight single-curtain installation over a doorway, the track length is the curtain width plus 1–2 feet on one side so the curtain can be pulled completely clear of the opening when not in use. A 6-foot track is sufficient for most single-doorway applications.

For larger enclosures — a U-shaped arrangement around a procedure table, for example — add up the perimeter of the area to be enclosed. A U-shaped enclosure with sides of 8 ft, 12 ft, and 8 ft requires 28 linear feet of track. Curved sections connect the straight runs at the corners. If you're unsure about the layout, Intech offers CAD design support for 2D layouts and 3D modeling — contact them before ordering if the room geometry is complex.

Curtain Sizing and Selection

The curtain needs to be sized to match the opening it covers, with enough overlap on each side to prevent gaps. For a standard 36" ADA-width doorway, a 48" wide curtain is the right choice — 6 inches of overlap on each side. For wider openings, add the corresponding width. The most common curtain length is 7 feet, which covers a standard 80" door height and keeps the bottom of the curtain at approximately 1" floor clearance — the standard for avoiding a radiation gap at the floor without causing a trip hazard.

Intech's lead curtains are available in protection levels of 0.25mm, 0.50mm, 0.75mm, and 1.0mm lead equivalency, constructed with a leaded-vinyl matrix core and a durable, easy-to-clean nylon outer layer. Stock colors are grey (112) and royal blue (108) in 4 ft × 4 ft, 4 ft × 6 ft, and 4 ft × 7 ft sizes — these ship within 4–6 weeks. Custom sizes and any of 18 available colors are manufactured to order and normally ship 4–6 weeks after order.

Curtains are also available as complete kits with tracks included, combining the curtain and hardware into a single order — useful when you're specifying a new installation from scratch and want to ensure the track and curtain are matched correctly.

Trim Chain: Getting the Height Right

One practical detail that's easy to overlook: the height of the track relative to the curtain length determines where the bottom of the curtain falls. In most installations the track is mounted at or near the ceiling, and the curtain needs to hang at a specific height — typically with 1 inch of floor clearance. If the curtain is shorter than the drop from the track to the correct hanging height, trim chain fills the gap.

Intech's trim chain is a light-duty zinc-plated steel chain made from 1/8" diameter solid steel wire, with links formed into a figure-eight shape and twisted 90° so the chain won't spin or jostle. It's sold in 10-foot lengths and can be cut on-site to exactly the length needed, so the curtain hangs at the correct height regardless of where the track is mounted. It's a small item but an important one — without it, a curtain mounted on a high ceiling track may hang several inches too high and leave a gap at the bottom that undermines the shielding.

Installation and Lead Times

Track installation is straightforward. A complete kit can typically be installed in under two hours — the process is comparable in complexity to mounting a wall-mounted TV or installing window curtains. Tracks normally ship at the same time as curtains, but can ship within 48 hours separately if advance installation is needed before the curtains arrive.
